ABSTRACT

The present disclosure relates generally to gaming systems, machines, and methods and, in particular, hidden symbol tracking. As an example, an electronic gaming machine is described that includes a set of reels, where each reel in the set of reels includes a plurality of symbol regions with at least one symbol provided therein, and where a first reel in the set of reels includes a hidden symbol that is capable of different presentations based upon having different lighting conditions applied thereto.

BACKGROUND

In some gaming machines, images, symbols, bonuses, or other incentivesare hidden from the player. The purpose of hiding such symbols orincentives is to increase the suspense of play and improve the player'soverall gaming experience. To hide these objects, gaming machines haveutilized a number of different internal techniques including mechanicaldoors that open to reveal a display, light curtains, electroluminescentdisplays, and image manipulations. As can be appreciated, it is fareasier to implement hidden symbol features in digital machines having adigital display as compared to traditional reel-based machines. Thereare, however, many players that still prefer playing mechanical machinesas compared to digital machines.

DETAILED DESCRIPTION

Embodiments of the present disclosure will be described in connectionwith gaming machines that operate using a traditional reel and symbolsprovided on the reel. While embodiments will be described in connectionwith such mechanical gaming machines, it should be appreciated thatembodiments of the present disclosure are not so limited. Rather,embodiments described herein can be used in any type of gaming machine,personal device, gaming system, or the like. For example, the variousgaming methods depicted and described herein can be executed with amechanical gaming machine, a digital gaming machine, or the like.Furthermore, a personal computing device, such as a smartphone, tablet,wearable device, etc. may also be configured to execute any of thefeatures depicted and described herein.

Embodiments of the present disclosure provide symbol tracking behind ahidden symbol on a reel strip by backlighting the symbol. In someembodiments, the backlighting may be provided for a hidden symbol withvariably colored backlights and may be made part of a paying combinationset.

As an example, the present disclosure provides a presentation in amechanical reel EGM of a set of symbols on physical reel strips whichmove synchronously during play (e.g., regular game play or bonus play)and are tracked with backlighting (or other preferred presentationmethod) while using certain colored backlighting to reveal a hiddenportion of a symbol which may be part of the symbol set. The symbol setsin the bonus, including the symbol sets with the hidden symbols, mayaward prizes during the bonus of a particular game. It should beappreciated, however, that the proposed disclosure can apply anymechanical-reel game feature that utilizes a hidden symbol that iscapable of being made visible. While described in connection with amechanical reel game feature, other game features can be modified tomake use of the alignment and/or preferred lighting described herein.

In some embodiments, the reels do not need to be in alignment before orduring rotation. Furthermore, embodiments described herein can beapplied to bonus play and/or game play at an EGM.

There are multiple ways to reveal hidden symbols. Existing games thatuse other forms of hidden symbol reveal features could be retrofitted toinclude the hidden symbol reveal feature described herein. The proposedmethod of revealing hidden symbols provides a very high quality andvisually attractive symbol, more-so than previous methods.

With reference initially to FIG. 1, details of an illustrative EGM 100will be described in accordance with at least some embodiments of thepresent disclosure. The components of the EGM 100, while depicted ashaving a particular configuration, is not necessarily limited to theexamples depicted herein. Rather, a device or system according toembodiments of the present disclosure may include one, some, or all ofthe components depicted in the EGM 100 and does not necessarily have toinclude all of the components in a single device.

Furthermore, although FIG. 1 only shows a single EGM 100, it should beappreciated that one or multiple EGMs 100 may be distributed throughouta casino property, a premises, or multiple premises. An EGM 100 maycorrespond to a stand-alone device or may be network-connected withother EGMs and/or a centralized gaming management system.

The EGM 100 may correspond to a type of device that enables playerinteraction in connection with playing games of chance. The illustrativeEGM 100 is shown to be a slot machine, which may enable a player toengage in a game of slots where payouts made to the player are based ona symbol combination that lands across a payline 112 after a set ofreels 108 has completed spinning. It should be appreciate that the EGM100 does not have to be embodied as a slot machine, but rather may beembodied as any type of machine that facilitates a game of chance.Furthermore, although the EGM 100 is shown as only having buttons asuser inputs, it should be appreciated that the EGM 100 may be providedwith a traditional slot arm to enable a player to pull the arm andactivate game play.

In some embodiments, the EGM 100 may also be provided with an exteriorhousing 104 and a front face including a top glass, a main display, anda belly glass. Main display or reel glass may be used to house the setof reels 108. In some embodiments, the reel glass may include individualwindows or single window which displays a single spinning reel in theset of reels 108.

Horizontal payline 112 is shown to span the windows and allow forwinning combinations. Although a single payline 112 is shown, it shouldbe appreciated that EGM 100 may be provided with multiple paylines 112,in which case the EGM 100 may provide multiple opportunities for winningcombinations. Top glass and belly glass may contain printed informationconveying various thematic or instructive details about the EGM 100.Glasses and may or may not be backlit so that information printed onthem is readily visible to gaming machine players. In addition, the EGM100 may be provided with a credit meter within or adjacent to the set ofreels 108. The credit meter may present primary game information such ascoin insert events (e.g., a 7-segment LED meter will increase its countin response to a player inserting a coin into a coin acceptor, a billinto a bill acceptor, or a ticket/voucher into a ticket/voucheracceptor). Player buttons are also shown to be provided between bellyglass and main display reel glass and allow the player to controloperation of EGM 100. A coin acceptor and a bill acceptor are providednear the play buttons as shown. Finally, a coin tray is provided nearthe bottom of the EGM 100 to collect coin pay outs from winning plays.

As mentioned, the set of reels 108 are provided behind windows and eachreel in the set of reels 108 may be configured to rotate or spinindependently of the other reels in the set of reels 108. Although FIG.1 illustrates the set of reels 108 as having three reels, it should beappreciated that the set of reels 108 may include a greater or lessernumber of reels without departing from the scope of the presentdisclosure.

With reference now to FIG. 2, additional details of the set of reels 108will be described in accordance with at least some embodiments of thepresent disclosure. The set of reels 108 are shown to include a firstreel 204 a, a second reel 204 b, and a third reel 240 c. Again, thenumber of reels 204 in the set of reels 108 should not be construed asbeing limited to three reels 204.

Each reel 204 is shown to include a plurality of symbols 216, 220distributed across a plurality of symbol regions 212 a-N, where N is aninteger number greater than or equal to two. Each reel 204 in the set ofreels 204 is shown to have an equal number of symbol regions 212 a-N asother reels 204, but such a configuration is not a requirement. Thetypes of symbols 216, 220 that are provided on a particular reel 204 mayvary depending upon the nature of the game provided by the EGM 100. Inthe depicted embodiment, each reel 204 include a number of traditionalsymbols 216 distributed among the symbol regions 212. In someembodiments, a reel 204 may be provided with an equal number oftraditional symbols 216 and symbol regions 212, meaning that each symbolregion 212 on a reel 204 includes one and only one symbol. Non-limitingtypes of symbols that may be provided as traditional symbols 216 include“7”, “Bar”, “Double Bar”, “Triple Bar”, cherries, fruits, or any otherpiece of graphical artwork.

FIG. 2 also shows the third reel 204 c as having at least one hiddensymbol 220 in one of the symbol regions 212. The hidden symbol 220 maybe provided with the ability to have its presentation altered inresponse to different lighting conditions, for example. While the thirdreel 204 c is the only reel 204 in FIG. 2 exhibiting the hidden symbol220, it should be appreciated that the hidden symbol 220 may be providedon one, some, or all of the reels in the set of reels 108. Moreover, areel 204 may be provided with more than one hidden symbol 220 withoutdeparting from the scope of the present disclosure. In the event that aparticular reel 204 include more than one hidden symbols 220, theplurality of hidden symbols 220 does not necessarily have to be of thesame type. Alternatively, as discussed herein, the hidden symbols 220may be of the same type, but do not necessarily have to have the samelighting condition applied thereto during any given game play event. Forinstance, two of the same hidden symbols 220 may have different lightingconditions applied thereto, causing one hidden symbol 220 to provide afirst presentation and another hidden symbol 220 to provide a secondpresentation that is different from the first presentation.

Each of the reels 204 may be configured to rotate around a commonrotational axis, although such a configuration is not required.Moreover, the reels 204 may be configured as traditional rotatingmechanical reels or digital reels that emulate a rotating mechanicalreel. Embodiments will be described in connection with a mechanicalreel-based EGM 100, but it should be appreciated that the disclosure isnot so limited.

With reference now to FIGS. 3A-C, additional details of a hidden symbol220 and its various presentations will be described in accordance withat least some embodiments of the present disclosure. FIG. 3A shows ahidden symbol 220 in the form of a SUPER DRUMROLL symbol. In a firstpresentation, the hidden symbol 220 has a first lighting conditionapplied thereto that causes the hidden symbol 220 to provide a firstpresentation to the player of the EGM 100. This particular presentationshows the text of “DRUMROLL” as being a white color whereas thebackground and surrounding graphics present stars. In some embodiments,the first presentation may be achieved by applying a first backlightingcondition where light of a first wavelength is used to illuminate thehidden symbol 220 from the backside of the reel strip 304. As will bediscussed in further detail herein, the construction of the hiddensymbol 220 on the reel strip 304 may be different from the constructionof other symbols 216 on the reel strip 216. As a non-limiting example,the hidden symbol 220 may be provided with a stack of differentlycolored films, where each layer in the stack of differently coloredfilms has a different graphic provided thereon. Alternatively oradditionally, the hidden symbol 220 may be provided with one or moreoptical elements that operate as a waveguide, lens, diffuser, or thelike that bends, shapes, reflects, or refracts light of different colorsin different ways, thereby creating different presentations of thehidden symbol 220.

As shown in FIG. 3B, the hidden symbol 220 is capable of providing asecond presentation that is different from the first presentation shownin FIG. 3A. This second presentation of the hidden symbol 220 may beachieved by applying a second lighting condition to the hidden symbol220. This particular presentation shows the text of “SUPER DRUMROLL” asbeing a color other than white. In some embodiments, the color of thetext in the second presentation may match or substantially correspond tothe color of lighting applied to the hidden symbol 220 frombacklighting. In this example, the stars that were previously presentedover the text of “DRUMROLL” are no longer presented. Rather, the text of“SUPER” is presented in the same overlapping area of the stars.

As shown in FIG. 3C, the hidden symbol 220 is capable of providing athird presentation that is different from the first presentation andsecond presentation. This third presentation of the hidden symbol 220may be achieved by applying a third lighting condition to the hiddensymbol. This particular presentation shows the text of “DRUMROLL” in acolor different from the colors of the “DRUMROLL” presentation in thefirst and second presentations. Furthermore, in the third presentationthe visibility of the stars above the text “DRUMROLL” is prominent andeffectively masks the visibility of the text “SUPER.”

As will be discussed in further detail herein, the hidden symbol 220 maybe capable of having multiple different presentations and thosepresentations may depend upon a lighting condition applied to the hiddensymbol 220, or more specifically the symbol region 212 in which thehidden symbol 220 is provided. In some embodiments, the game play may bemodified or dependent upon the type of presentation provided by thehidden symbol 220. More specifically, if the hidden symbol 220 lands onthe payline 112 and is part of a winning combination, then the type ofpresentation currently provided by the hidden symbol 220 may be used todetermine additional game play features. For instance, if the hiddensymbol 220 lands on the payline 112 as part of a winning combinationwith the first presentation as shown in FIG. 3A, then the player may beprovided with a first win amount, a first bonus, a first number of bonusspins, or some other type of game play reward. If the same hidden symbol220 lands on the payline 112 as part of a winning combination, but witha second presentation as shown in FIG. 3B, then the player may beprovided with a second win amount, a second bonus, a second number ofbonus spins, or some other type of game play reward that is differentfrom when the same hidden symbol 220 landed on the payline 112 with thefirst presentation. Similarly, if the hidden symbol 220 lands on thepayline 112 as part of a winning combination, but with a thirdpresentation as shown in FIG. 3C, then the player may be provided with athird win amount, a third bonus, a third number of bonus spins, or someother type of game play reward that differs from the other rewardsprovided for different presentations of the hidden symbol 220.

FIGS. 4A-C illustrate a hidden symbol 220 exhibiting differentpresentations in accordance with at least some embodiments of thepresent disclosure. The hidden symbol 220 is shown to include a firstsymbol portion 404 and a second symbol portion 408. In some embodiments,the first symbol portion 404 and second symbol portion 408 may beadjacent to one another, but not overlapping. In some embodiments, thefirst symbol portion 404 may partially or completely overlap the secondsymbol portion 408. Furthermore, although FIGS. 4A-C illustrate thehidden symbol 220 as having only two symbol portions 404, 408, it shouldbe appreciated that the hidden symbol 220 may have more than two symbolportions without departing from the scope of the present disclosure.

FIG. 4A illustrates the hidden symbol 220 exhibiting a firstpresentation. In this presentation, graphical content in both the firstsymbol portion 404 and second symbol portion 408 are made visible to theplayer of the EGM 100. In some embodiments, the first portion 404 mayinclude graphical content that is responsive to and becomes visible whenbacklight with a first type of light (e.g., red light). It should beappreciated that the graphical content of the first portion 404 maybecome visible when backlight with a second type of light (e.g., whitelight or some other light that also includes red light within itsspectrum). Likewise, the second portion 408 may include graphicalcontent that is responsive to and becomes visible when backlight with athird type of light (e.g., blue light). It should also be appreciatedthat the graphical content of the second portion 408 may become visiblewhen backlight with the second type of light (e.g., the white light orsome other light that also includes blue light in its spectrum). Becausethe graphical content of the first and second portions 404, 408 areresponsive to at least one common lighting condition (e.g., applicationof white backlight), there may be a presentation of the hidden symbol220 that displays graphical content from both the first and secondportions 404, 408.

As a non-limiting example, the hidden symbol 220 may be construed with aplurality of layers of multi-colored ink, with certain colors of inkbeing provided in the first portion 404 of the hidden symbol 220 andother colors of ink being provided in the second portion 408 of thehidden symbol. In some embodiments, red and blue symbol colors can beprinted with inkjet printers onto the reel strip 304, which allows thedifferent colors of light to portray the desired messaging of thegraphical content printed by the inkjet printers. It may be possible torun the reel strip 304 through the printer once for the blue color, andonce again for the red color, and perhaps once more for any finishingelements. The blue color may be printed in the first portion 404, forexample, whereas the red color may be printed in the second portion 408.Then any finishing elements may be printed over both the first andsecond portions 404, 408.

However, FIG. 4B shows a situation where the content of the firstportion 404 is not visible, but the content of the second portion 408 isvisible. This may correspond to a situation where the hidden symbol 220is backlight with the third type of light, but not with the first orsecond type of light. Thus, because the second portion 408 is responsiveto the third type of light, the graphical content of the second portion408 is made visible, but the graphical content of the first portion 404is not made visible.

Conversely, FIG. 4C shows a situation where the content of the firstportion 404 is visible, but the content of the second portion 408 is notvisible. This may correspond to a situation where the hidden symbol 220is backlight with the first type of light, but not with the second orthird type of light. Thus, because the first portion 404 is responsiveto the first type of light, the graphical content of the first portion404 is made visible, but the graphical content of the second portion 408is not made visible.

With reference now to FIG. 5, additional details of a reel assembly 500will be described in accordance with at least some embodiments of thepresent disclosure. The reel assembly 500 may be used to physicallysupport and impart motion of the reel strip 304 within the EGM 100. Thereel strip 304 may be laid out across a frame 504, that is rotatableabout an axis of rotation. In some embodiments, the frame 504 provides acavity 512 at its interior. The cavity 512 may accommodate other EGM 100components, such as backlighting and related control electronics. Insome embodiments, the frame 504 is mountable to the housing 104 of theEGM 100 via a frame mount bracket 508. The frame mount bracket 508 maybe connected with the frame 504 using any type of rotatable member, suchas a bearing, hub, pin/hole, etc. In some embodiments, rotation of theframe 504 is driven by an electronic drive motor, such as a servo motoror the like. In such an embodiment, the rotation of the frame 504 may bestopped by inertial forces, braking forces, or forces applied by theelectronic drive motor. Alternatively, the frame 504 may be rotated byforces imparted from a traditional mechanical handle or lever that isconnected with each reel assembly 500 through a mechanical or gearedlinkage. In either configuration, a position of symbols 216, 220 orassociated symbol regions 212 may be tracked by the EGM 100 as the frame504 rotates around its axis of rotation. Such motion tracking may beachieved with the use of a rotational encoder that is configured tocount both absolute rotations and increments of rotation of the frame504, possibly relative to a position of origin on the reel strip 304.

FIG. 6 illustrates a lighting system 600 that may be used to applyselective lighting conditions to various symbol regions 212 on the reelstrip 304 in some embodiments. In particular, the lighting system 600 isshown to include a light-mount substrate 604 on which a number of setsof lights 608 a, 608 b, 608 c are mounted. The lighting system 100 isfurther shown to include a fiber optic bundle 612 that electricallyconnects the sets of lights 608 a, 608 b, 608 c with a light controlcircuit 616. The various components of the lighting system 600 may beprovided on a frame 620 that is mountable to the housing 104 of the EGM100.

In some embodiments, the light substrate 604 is not movable orrotatable. In some embodiments, the light substrate 604 may be movableor rotatable, in which case the fiber optic bundle 612 may be replacedwith an electrical interface that facilitates the connection between arotating member, in the form of the light substrate 604, and a fixedmember, in the form of the light control circuit 616. In someembodiments, the light control circuit 616 may include an interface thatallows connectivity with a lighting controller or similar logic circuitin the EGM 100. In some embodiments, the light control circuit 616 mayinclude the light controller and the interface to the controller mayconnect with a gaming controller, or the like.

FIG. 6 shows the lighting system 600 to have a first set of lights 608a, a second set of lights 608 b, and a third set of lights 608 c. Itshould be appreciated that a lighting system 600 may have a greater orlesser number of sets of lights without departing from the scope of thepresent disclosure. In some embodiments, the entirety of the lightingsystem 600 may be mountable within the cavity 512 of the reel assembly500. Such a configuration may allow the sets of lights 608 a, 608 b, 608c to selectively apply different lighting conditions to the symbolregions 212 on the reel strip 304. As will be discussed in furtherdetail herein, operation of the lighting system 600 may be coordinatedwith operation of the reel assembly 500 such that selected symbolregions 212 on the reel strip 304 are backlight during rotation. In someembodiments, the different sets of lights 608 a, 608 b, 608 c may beselectively activated and deactivated to consistently apply apredetermined lighting condition to some selected symbol regions 212 ona reel strip 304, but not other symbol regions 212 on the same reelstrip 304. In some embodiments, the selected symbol region 212 that hasthe predetermined lighting condition applied thereto may contain asymbol 216 or a hidden symbol 220.

In some embodiments, each set of lights 608 may have a plurality oflight-emitting devices. Each light-emitting device in the plurality oflight-emitting devices may be configured to apply a different lightingcondition. Alternatively or additionally, the set of lights 608 may havea first subset of lights (e.g., white LEDs) configured to apply a firstlighting condition, a second subset of lights (e.g., red LEDs)configured to apply a second lighting condition, and a third subset oflights (e.g., blue LEDs) configured to apply a third lighting condition.

With reference now to FIGS. 7A-C, additional details of the coordinationbetween operation of the lighting system 600 and operation of the reelassembly 500 will be described in accordance with at least someembodiments of the present disclosure. Referring initially to FIG. 7A, afirst state of a reel 204 is depicted. In this first state, the reelstrip 304 may be positioned at a first position such that a selectedsymbol region 732 from among the plurality of symbol regions 212 has apredetermined lighting condition applied thereto. Specifically, the reel204 is provided with a motor controller 708 and lighting controller 720that operate in coordination with one another to apply the predeterminedlighting condition to the selected symbol region 732 as the reel strip304 rotates 716.

In some embodiments, the motor controller 708 and lighting controller720 may be synchronized with one another through a game controller 704.In some embodiments, the game controller 704 may include instructions orcircuitry that enable synchronous operation of the motor controller 708and lighting controller 720.

Responsive to a first control signal from the game controller 704, themotor controller 708 may engage a motor 712 or the like that impartsrotation 716 on the reel strip 304. The lighting controller 720 mayoperate in response to a second control signal from the game controller704. Based on the second control signal, the lighting controller 720 mayprovide instructions or control signals to a lighting driver 724 thatselectively activates and deactivates particular sets of lights 608.Communications between the lighting driver 724 and sets of lights 608may be provided by the fiber optic bundle 612, as an example. In someembodiments, the lighting driver 724 and/or lighting controller 720 mayboth be provided in the light control circuit 616.

The motor 712 may be configured to rotate 716 the reel strip 304 througha geared coupling, with one or more sprockets, with a chain, with abelt, or the like. Said another way, any type of mechanical linkage canbe used to couple the motor 712 to the to the frame 504 of the reelassembly 500 to facilitate rotation of the reel strip 304.

As shown in FIG. 7B, when the reel strip 304 is rotated to a secondposition, the selected symbol region 732 may move relative to the setsof lights 608 and overlap a different set of lights 608 than when it wasin the first position. The set of lights 608 now being overlapped by theselected symbol region 732 may be activated, by issuance of a controlsignal from the lighting controller 720, whereas the set of lights 608that were previously overlapped but no longer overlapped by the selectedsymbol region 732 may be deactivated. In some embodiments, each set oflights 608 may apply the same predetermined lighting condition to theselected symbol region 732 by emitting a particular wavelength of light728. In some embodiments, different sets of lights 608 may applydifferent predetermined lighting conditions as the selected symbolregion 732 rotates over each different set of lights 608. In the latterscenario, if the selected symbol region 732 contains a hidden symbol220, then the presentation of the hidden symbol 220 may alter inresponse to having different lighting conditions applied thereto. In theformer scenario, if the selected symbol region 732 contains a hiddensymbol 220, then the presentation of the hidden symbol 220 may appearconsistent as the reel strip 304 rotates. In some embodiments, the setsof lights 608 may be activated and deactivated based on a rotationalspeed of the reel strip 304 so as to make each backlight symbol appearas though it is consistently light during rotation.

In some embodiments, the predetermined lighting condition applied to asymbol may be determined at the game controller 704, based on a desiredgame play feature to provide for the hidden symbol 220. In someembodiments, the predetermined lighting condition applied to a symbolmay be determined randomly or by the lighting controller 720. It shouldbe appreciated that the game controller 704, motor controller 708, andlighting controller 720 may be provided as separate components or may beprovided as a single controller without departing from the scope of thepresent disclosure.

As shown in FIG. 7C, while the reel strip 304 continues rotating into athird position, the selected symbol region 732 now overlaps anotherdifferent set of lights 608. Again, the set of lights 608 that werepreviously activated and had the selected symbol region 732 overlappingmay become deactivated so that the other non-selected symbol region 212does not have the predetermined lighting condition applied thereto.

While FIGS. 7A-C show an example of a reel strip 304 having a singleselected symbol region 732, it should be appreciated that the reel strip304 may have multiple selected symbol regions 732 that have the same ordifferent predetermined lighting conditions applied thereto. Themultiple selected symbol regions 732 may or may not both have hiddensymbols 220 or traditional symbols 216.

With reference now to FIG. 8, additional details of an EGM 100 will bedescribed in accordance with at least some embodiments of the presentdisclosure. The EGM 100 is depicted to include a processor 804, memory808, a network interface 812, a user interface 816, a ticket issuancedevice 836, a ticket acceptance device 840, a cash in device 844, and acash out device 848.

With reference now to FIG. 9, a gaming method will be described inaccordance with at least some embodiments of the present disclosure. Themethod begins when game play begins (step 904). This step may involvereceiving coins, cash, a ticket, a voucher, or the like at the EGM 100and then updating the credit meter 824 to reflect that the player of theEGM 100 has game play credits for playing a game of chance at the EGM100. Game play may also be initiated when the player, having sufficientgame play credits, presses a “spin” button or pulls a handle of the EGM100, indicating a desire to initiate the game play. In some embodiments,where the EGM 100 is a slot machine, the game play corresponds toinitiating the rotation of the reels 204 in the set of reels 108.

As game play proceeds, the method continues by coordinating theoperation of the motor controller(s) 708 with operation of the lightingcontroller(s) 720 (step 908). In some embodiments, coordination mayinvolve sending concurrent control signals to each of the motorcontrollers 708 and lighting controllers 720 indicating that aparticular game play feature is desired. Furthermore, the operation ofthe controllers may be achieved by tracking a rotation of the mechanicalreels and reporting the rotational position thereof to the lightingcontroller(s) 720, thereby enabling the lighting controller(s) 720 toappropriately apply backlighting 856 to the rotating reels.

The method continues by determining that a hidden symbol 220 is to bedisplayed with a predetermined presentation (step 912). This decisionmay be made by the game instruction set 820 or may be made based on anoutcome of the game play. For instance, it may be possible to determinethat a hidden symbol 220 is to be displayed with a predeterminedpresentation during a bonus spin when the hidden symbol 220 lands on thepayline 112 as part of a winning combination during normal game play.The bonus spin may correspond to an extension of the game play that wasinitiated at step 904.

The method continues by determining the appropriate lighting conditionto apply to the hidden symbol 220 to achieve the predeterminedpresentation (step 916). Appropriate lighting conditions may correspondto application of backlight of a particular color/wavelength,application of white backlight, application of a particular intensity oflight, application of flashing lights, etc.

Then, as the reel 204 rotates, the appropriate lighting condition isapplied to the hidden symbol 220 (step 920). This effectively causes thehidden symbol 220 to have the predetermined presentation with the addedeffect of rotation. In other words, the hidden symbol 220 has thepredetermined presentation as it rotates around and is presented to theplayer of the EGM 100.

When the rotation of the reels 204 are complete, the method continues bydetermining a payout or prize for the player (step 924). In someembodiments, the payout or prize may depend upon the predeterminedpresentation of the hidden symbol 220 and whether or not the hiddensymbol 220 landed on the payline 112 as part of a winning combination atany point during game play. The method then proceeds with the EGM 100providing the payout or prize, if any, and updating the credit meter 824as appropriate (step 928).

With reference now to FIG. 10, another gaming method will be describedin accordance with at least some embodiments of the present disclosure.The method begins by determining a position of a symbol, such as ahidden symbol 220, on a reel that is to receive a presentationadjustment (step 1004). A presentation adjustment can be provided for ahidden symbol 220 by applying a different lighting condition to thehidden symbol 220 than was previously applied to the hidden symbol 220.

The method continues by applying the presentation adjustment to thesymbol region 212 in which the symbol is positioned (step 1008). Part ofthis step may involve not applying the presentation adjustment to othersymbol regions on the reel strip 304. Thus, the symbol region 212 thatreceives the presentation adjustment may be considered a selected symbolregion 732.

The method then continues by determining if the symbol receiving thepresentation adjustment has landed on the payline (step 1012). In someembodiments, this step may also include determining whether or not thesymbol landing on the payline 112 is part of a winning combination ofsymbols that landed on the payline 112. If the query of step 1012 isanswered negatively, then the EGM 100 will be made ready for the nextgame (step 1016).

Conversely, if the query of step 1012 is answered positively, then themethod proceeds by determining a payout based on the presentationadjustment provided to the symbol (step 1020). This step may alsoinclude assessing the other symbols on the payline 112, alone or incombination with the symbol receiving the presentation adjustment.

The method then continues by providing the player with the determinedpayout and any other player awards as determined in step 1020 (step1024). The other types of awards that may be provided to the playerinclude additional bonus spin opportunities, additional play credits,etc.

With reference now to FIG. 11, another gaming method will be describedin accordance with at least some embodiments of the present disclosure.The method begins with the initiation of a game play (step 1104). Gameplay may be initiated in response to a player inserting cash, coins,tickets, vouchers, etc. into the EGM 100 and then engaging anappropriate input (e.g., pressing a spin button or pulling a handle) toinitiate a new game play at the EGM 100.

The method continues by determining that a hidden symbol 220 has landedon a payline 112 when the set of reels 108 stopped spinning (step 1108).In some embodiments, this step may also require that the hidden symbol220 be part of a winning combination set before proceeding to additionalor extended game play. The logic controlling whether additional spinsare going to be allowed at the EGM 100 may be provided by the gameinstruction set 808, for example.

If extended game play is in order (e.g., due to the hidden symbol 220landing on the payline 112 as part of a winning symbol combination),then the method continues by determining the number of bonus spins toaward to the player (step 1112). In some embodiments, the number ofbonus spins awarded to a player may depend upon the presentation of thehidden symbol 220 when it landed on the payline 112. For instance, ifthe hidden symbol 220 has a first presentation due to having a firstlighting condition applied thereto, then the player may simply beawarded a single bonus spin. However, if the hidden symbol 220 has asecond presentation due to having a second lighting condition appliedthereto, then the player may be awarded multiple bonus spins.

The method will continue by updating the bonus spin availability for theplayer (step 1116). This update may be achieved by updating the creditmeter 824 or some other record in the EGM 100 that control whether ornot a player is allowed to play a bonus spin. The bonus spinavailability may be updated to reflect the full amount of bonus spinsawarded in step 1112, as long as the full amount of bonus spins do notexceed a predetermined threshold number of bonus spins.

The method then continues by allowing the player to play a bonus spin(step 1120). After the bonus spin is completed, the method continues bydetermining if the hidden symbol 220 has again landed on the payline 112(step 1124). If not, then the payout or bonus total to be paid to theplayer is determined (step 1140) and the appropriate payout is providedto the player, either in the form of additional play credits, in theform of coins, and/or in the form of a ticket (step 1144).

Referring back to step 1124, if the hidden symbol 220 again lands on thepayline at the end of the bonus spin, then the method continues bydetermining if additional bonus spins are still available to the player(step 1128). For instance, this step may involve determining whether ornot the player has earned another bonus spin or multiple bonus spinsbased on the hidden symbol 220 again landing on the payline 112. Thisstep may also involve determining if the player has an additional bonusspin available. If the query is answered no, then the method proceeds tostep 1140.

If the player is awarded additional bonus spins, then the methodcontinues to determine if the player has reached a bonus spin cap (step1132). In some embodiments, the bonus spin cap may correspond to apredetermined maximum threshold of bonus spins. If the bonus spin caphas been reached, then no further bonus spins can be awarded to theplayer and the method proceeds to step 1120 to only allow bonus spinsbased on the current number of available bonus spins previously awardedto the player. If the cap has not yet been reached, then the methodproceeds by determining the additional bonus spins that can be awardedto the player (step 1136). Thereafter, the method proceeds to step 1116.

It should be appreciated that any of the above-described methods can beprovided by an EGM 110 having a digitally-generated set of reels 204 ormechanical reels 204 that are configured to rotate around an axis ofrotation. In a digital representation of reels 204, the game may beplayed on a traditional EGM 100 in a casino or on a personal computingdevice carried by a player. An example of such a personal computingdevice may include a smartphone, tablet, PC, or the like.
